Declarationfunction LoadFromFileGIF(const FileName: WideString): integer;
Loads an image from a GIF file (87a, 89a or animated GIF).FileName
is the file name including extension.
Returns the number of images contained in GIF file (if this is an animated GIF) or -1 if an error was encountered while loading, such as the file not being GIF format (Aborting
will be true). Loading errors due to a file not being available will raise an exception.
- You can abort loading by setting Aborting
- If AsyncMode
=True the result will always be -1
- If you are loading from a multi-frame GIF, enable GIFFrameCaching
to speed up loading
- By default, GIF_RawLoad
is enabled, so the frame returned will be merged to ensure it is a valid image (contains needed content from prior frames)
Example// Loads the third frame of an animated gif
ImageEnView1.IO.Params.GIF_ImageIndex := 2;
